Abstract : plant responses to salt stress via a complex mechanism, including sensing and transducing the stress signal, activating the transcription factors and the corresponding metabolizing genes. since the whole mechanism is still unclear, this review emphasize the biochemical events during the plant adaptation to salt stress referring to an index of importance : the homeostasis in cytoplasm, the biosynthesis of osmolytes and the transport of water. most of these biochemical events were elucidated by study of halophyte and salt - sensitive mutations, also many important genes involved were cloned and used to generate stress - tolerance phenotypes in transgenic plants. on the other hand, about the molecular mechanism in signal transduction, the research of arabidopsis mutations and yeast functional complementation provided helpful traces but not full pathway
摘要植物對鹽脅迫的耐受反應是個復雜的過程，在分子水平上它包括對外界鹽信號的感應和傳遞，特異轉錄因子的激活和下游控制生理生化應答的效應基因的表達.在生化應答中，本文著重討論負責維持和重建離子平衡的膜轉運蛋白、滲調劑的生物合成和功能及水分控制.這些生理生化應答最終使得液泡中離子濃度升高和滲調劑在胞質中積累.近年來，通過對各種鹽生植物或鹽敏感突變株的研究，闡明了許多鹽應答的離子轉運途徑、水通道和物種特異的滲調劑代謝途徑，克隆了其相關基因並能在轉基因淡水植物中產生耐鹽表型;另一方面，在擬南芥突變體及利用酵母鹽敏感突變株功能互補篩選得到一些編碼信號傳遞蛋白的基因，這些都有助於闡明植物鹽脅迫應答的分子機制。 -
High salt stress disrupts homeostasis in water potential and ion distribution. this disorder of homeostasis occurs at both the cellular and the whole plant levels. drastic changes in ion and water homeostasis lead to molecular damage, growth inhibition and even death
滲透脅迫、離子脅迫及其造成的一系列次級脅迫如氧化脅迫等，嚴重干擾植物體內業已存在的細胞及整株水平上的水分及離子穩態，造成植物細胞分子損傷，生長減緩甚至死亡。 -
Salinity stress disrupts the homeostasis in water potential and ion distribution, results in osmotic and ionic stress in plants. it can arose growth arrest, and in some extreme conditions, even death of plants
鹽脅迫能夠破壞植物細胞的水勢均衡和離子均衡狀態，引起高滲脅迫和離子脅迫，使植物生長延滯，甚至死亡。 -
High concentration of salinity disrupts the homeostasis in ion distribution and water potential, results in osmotic stress and further leads to the damage on various molecules, such as protein, nucleotide acid etc. it can arose growth arrest, and in some extreme conditions, even death of plants
鹽分過高破壞了植物體內業已存在的均衡狀態，引起細胞的滲透失衡，造成細胞失水，因而鹽脅迫下，保持細胞水分均衡是植物對抗鹽脅迫的重要策略之一。
